REPLACEABLE FRICTIONALLY SUPPORTED BIRDS NEST Henry N ovack, Brooklyn, N. Y. Application October 26, 1939, Serial No. 301,487

' 2 Claims. (01. 119-45) This invention relates to a replaceable frictionally supported nest for bird cages designed to be used in the breeding of birds of various kinds, and particularly canaries.

An object of this invention is to provide a combination birds nest having'an adapter or supporting member permanently secured to a cage and having a nest body made of fibrous materials and manufactured at a low cost so that it may be in easily removed when covered with excreta'and thrown away, and a new nest body inserted in the adapter.

Another object of this invention is to provide a combination birds nest having an adapter or 15 supporting member permanently secured to a cage and having a nest body made of fibrous materials, the said nest body having'a fabric binding secured to the upper edge portion thereof, the said binding being secured by tightly stitching .10 the lower edge of the binding to the nestbody whereby the binding above the stitched edge projects outwardly and forms a means for augmenting the frictional engagement between the nest body and the supporting member.

25 With'the above and other objects in view, the invention will be hereinafter more particularly described, and the combination and arrangement of parts will be shown in the accompanying drawings and pointed out in the claims which form 30 part of this specification.

Reference will now be had to the drawings, wherein like numerals of reference designate corresponding parts throughout the several views, in which: v

ported therein, the view being on an enlarged scale.

Figure 6 shows an enlarged fragmentary detail of the adapter and nest body shown in Figure 5. v5

In the illustrated embodiment of the invention the numeral l0 indicates a replaceable frictionally supported nest for bird cages comprising an adapter or supporting member H having an aperture l2 centrally thereof. As best shown in 10 Figure 2, the aperture I2 is defined by a lateral flange 1 I3 of annular form and which has been formed by extending the lower edge portion of the supporting member inwardly all around.

As shown in Figures 1 and 2 the circular wall of the supporting member I I has two tongues l4,

l4 pressed therefrom. As shown in Figure 1, the tongues Hi have been bent around two vertical bars l5; l5 extending from a horizontal rail l6 of a bird cage and serve to effectively hold the supporting member to the cage. The supporting member l-I may have a flattened portion H to facilitate alinement with the bars l5 of the cage.

As shown in Figure 2, a nest body 20 preferably comprising inner and outer layers of loosely felted fibrous materials held in unitary relation in any suitable manner has a ribbon-like cover- The covering 2| .is preferably of annular form and of U-shaped cross-section and is designed to entirely conceal the upper portion of the nest body and to partly conceal the inner and outer surfaces of the nest body at the upper edge of the nest body.

The nest body 20 is .of semi-spherical form and of a size to permit entranceinto the supporting member with the upper portion of the nest 'bodyfrictionally retained by the flange l3 and so that it may be removed from the supporting member by a slight upward pressure against the 40 bottom surface of the nest body.

The upper edge portion of the nest body 20 will preferably be covered with a fabric binding 2| Which'may be secured by stitching 22 while folded over the inner and outer faces of the nest body.

at its upper edge. One edge of the platform 2! has been turned downwardly, forming a rightangular extension 28. Arms 29, having substantially U-shaped ends 30, have been integrally secured to the platform 2'! below its lower surface. The arms extend outwardly beyond the right-angular extension 28 so as to be adapted for engagement with a rectangular rail of a bird cage and with the wall extension 28 in contact with one face ofa wall of the cage.

As shown in Figure 4, I have provided a modified platform type supporting member 3| having an aperture 32 centrally thereof. The aperture 32 is defined by a vertical flange 33 of annular form. Apertures 34 shaped like slots of bayonet joints have been provided in diametrically "opposite sides of the flange 33. The supporting member 3! has a platform 31 at its-upper elevation and which is built with a right-angular extension 38 and with arms 39 having substan tially U-shaped ends 4%] similar to that shown in Figure 3. The arms extend outwardly beyond the righteangular extension 38 so as to be adapted for-engagement with a rectangular rail 4! of a bird cage and with the wall extension 38 in contact with one face of a wall of the cage, the wall being made up of bars 42.

A latch 43 has been pivotally mounted on a headed ,pin 44 in the extension 38. The latch :43 has a substantially semi-circular opening 45 designed for engagement with a headed pin 46 in the extension 38. The latch may have a handle 41 angularly positioned in its free end.

It is to be noted that the latch 43 has been mounted in spaced parallel relation with the extension 38, the spacing being substantially the same as the thickness of the bars 42 of the cage. The modified platform type supporting member 3! may thus be mounted on the bird cage with the extension 38 in contact with one face of a wall of the cage and by rotating the latch on the opposite face of the wall, the platform and nest becomes securely locked to the cage.

As shown in Figure 5, I have provided an adapter 50 comprising an annular metallic member of a height substantially greater than the height of the vertical flange 33 in the modified platform type supporting member 3|. I have provided headed pins 52 secured to the metallic member '5! on diametrically opposite sides thereof and facing outwardly. The pins 52 are positioned so as to fit into the apertures 34 in the The outer circumference of the adapter ,50 is slightly smaller than the inner circumference of the vertical flange 33 so as to readily enter therein.

As best shown in Figure 6, the lower edge of the member 5! has been extended inwardly all around -to form a lateral flange 53 of considerab e surface area and so that when a nest body .20 is inserted into the adapter 50, the nest body will be retained and supported by the adapter. It is to be noted that the lower edge of the ribbon-like fabric 2| is stitched tightly by the line ,of stitching 22 and causes the fabric above the stitched edge to project outwardly of the nest body into engagement with the flange 53. This interengaging of the nest body and the adapter augments the frictional grip by which the nest body is supported.

The user may grip the nest 2D and the lower edge portion of theadapter 50 and mount the nest 20 and the adapter 58 inside the flange 33, with .the headed ins 52 inside the bayonet slots 34, and by partial rotation of the said pins in the 'on the same date.

said slots, cause the nest 20 and adapter 50 to be secured in unitary relation with the platform type supporting member 3|.

The importance of the easily detachable bayonet connection is that it makes possible for the breeder to quickly remove the nest body only from the cage when transferring eggs deposited therein, and replacing with artificial eggs, with the viewpoint'of having all the eggs hatched This transfer is accomplished without disturbing the supporting mem- In prior practice, it was necessary for the breeder to insert his hand into the nest Ltoremove-the natural eggs and replace them withartificial eggs. In many instances the natural eggs .were destroyed during such removal. It is to be noted that the latch 43 when in locked position to the bars of the cage prevents vibration and holds the platform-nest firmly when the bird hops into and out of the nest. This non-vibratable feature serves a very useful purposezin the'hatching of canary eggs, as experiencehas shown that continuous vibration of a nest containing .eggs to be hatched destroys'life in the eggs.

In accordance with the patent statutes I have described and illustrated the preferred embodiments-of my invention, but it will be understood that various changes and modifications can be made therein'without departing from the spirit of the invention as defined by the appended claims.
